This pattern used to create an `llvm.func` op, then check additional requirements and return "failure". This commit moves the checks before the creation of the replacement op, so that no rollback is necessary when one of the checks fails. Note: This is in preparation of the One-Shot Dialect Conversion refactoring, which removes the rollback functionality.
